FIELD OF THE DISCLOSURE

The disclosure is related to consumer goods and, more particularly, tomethods, systems, products, features, services, and other items directedto media playback or some aspect thereof.

BACKGROUND

Digital music has become readily available due in part to thedevelopment of consumer level technology that has allowed people tolisten to digital music on a personal audio device. The consumer'sincreasing preference for digital audio has also resulted in theintegration of personal audio devices into PDAs, cellular phones, andother mobile devices. The portability of these mobile devices hasenabled people to take the music listening experience with them andoutside of the home. People have become able to consume digital music,like digital music files or even Internet radio, in the home through theuse of their computer or similar devices. Now there are many differentways to consume digital music, in addition to other digital contentincluding digital video and photos, stimulated in many ways byhigh-speed Internet access at home, mobile broadband Internet access,and the consumer's hunger for digital media.

Until recently, options for accessing and listening to digital audio inan out-loud setting were severely limited. In 2005, Sonos offered forsale its first digital audio system that enabled people to, among manyother things, access virtually unlimited sources of audio via one ormore networked connected zone players, dynamically group or ungroup zoneplayers upon command, wirelessly send the audio over a local networkamongst zone players, and play the digital audio out loud acrossmultiple zone players in synchrony. The Sonos system can be controlledby software applications running on network capable mobile devices andcomputers.

Like other electronic systems, the Sonos system is sold in retailstores. In the retail environment, point-of-sale (POS) displays arecommonly used to draw a customer's attention toward a product. A POSdisplay may demonstrate the capabilities of a product. However, suchdemonstrations may be generic in that one customer's experience with aPOS display is the same as or similar to another customer's experience.Additionally, a POS display may be difficult to locate or a customer maynot even know that a POS display is in the retail store. As a result, acustomer may not have a satisfactory experience with a POS display andconsequently, may not have a satisfactory experience with the productitself.

II. Example Operating Environment

Referring now to the drawings, in which like numerals can refer to likeparts throughout the figures, FIG. 1 shows an example system 100 thatincludes a point-of-sale-display (POS-display) in which one or moreembodiments disclosed herein can be practiced or implemented. It isunderstood that the embodiments described herein are not limited for usewith a POS display, but rather may be useful in a system where aconnection between a playback media system and a portable computingdevice are made.

The example system 100 may include: a POS display 110, a portablecomputing device 130, a data network 140, a local server 145, a mediasystem server 150, and a content provider server 152. The POS display110 may include a media system that may include: zone players 112, 114,and 116, a controller 118, and a playback network 120. In otherembodiments, the POS display may also include the local server 145. Itshould be understood that the example system 100 may include other POSdisplays, portable computing devices, controllers, media system servers,content provider servers, local servers, and data networks, and/or othernetwork elements without departing from the present invention.

The portable computing device 130 may be a smartphone or a tabletdevice, among other portable computing devices. Some aspects of theportable computing device 130 will be discussed below with respect tocontroller 500 of FIG. 5 . The zone players 112-116 are media playbackdevices that may provide audio, video, and/or audiovisual output. Thezone players 112-116 may be configured in zones. For example, the zoneplayers 112-114 may form a first zone, and the zone player 116 may forma second zone. Other zone configurations are certainly possible. Thecontroller 118 is a device that may control the media system (e.g., thezone players 112-116 and/or other controllers). For example, thecontroller 118 may control zone configurations, among otherconfigurations. The zone players 112-116 and the controller 118 may formthe playback network 120 (as discussed further below). The playbacknetwork 120 may be an “ad-hoc” network or a “mesh” network, among othernetwork types.

The POS display 110 may communicate with the portable computing device130, the local server 145, the media system server 150, and the contentprovider server 152 via the data network 140. Further, the POS display110 may communicate with the local server 145 directly. The portablecomputing device 130 may communicate with the local server 145, the POSdisplay 110, the media system server 150, and the content providerserver 152 via the data network 140. Additionally, the portablecomputing device 130 may communicate with the media system server 150and the content provider server 152 indirectly via communicating withthe POS display 110. The portable computing device 130 may communicatedirectly with the POS display 110. The zone players 112-116 and thecontroller 118 may use the playback network 120 to communicate with oneanother.

The example system 100 may be implemented, for example, in a retailstore (e.g., having a POS display), a restaurant, or a coffee shop,among other public environments. In one embodiment, the data network 140may include a public wireless network provided by a public entity. ThePOS display 110 may be a demonstration display where customers mayinteract with the media system of the POS display 110, for example,before purchasing a media system or individual devices (e.g., zoneplayers or controllers). A customer may interact with the POS display110 via his/her smartphone (e.g., the portable computing device 130). Inanother example, the POS display 110 may be part of an audio system thatan environment provides to customers for their use and enjoyment. Theexample system 100 need not be implemented in a setting where the mediasystem is for sale. Some aforementioned elements of the example system100 are discussed in greater detail below.

a. Example Zone Players

FIGS. 2A, 2B, and 2C show example types of zone players. Zone players200, 202, and 204 of FIGS. 2A, 2B, and 2C, respectively, can correspondto any of the zone players 112-116 of FIG. 1 , for example. In someembodiments, audio is reproduced using only a single zone player, suchas by a full-range player. In some embodiments, audio is reproducedusing two or more zone players, such as by using a combination offull-range players or a combination of full-range and specializedplayers. In some embodiments, each zone player 200-204 may also bereferred to as a “smart speaker,” because each may contain processingcapabilities beyond the reproduction of audio, more of which isdescribed below.

FIG. 2A illustrates the zone player 200 that includes sound producingequipment 208 capable of reproducing full-range sound. The sound maycome from an audio signal that is received and processed by the zoneplayer 200 over a wired or wireless data network. The sound producingequipment 208 may include one or more built-in amplifiers and one ormore acoustic transducers (e.g., speakers). A built-in amplifier isdescribed more below with respect to FIG. 4 . A speaker or acoustictransducer can include, for example, any of a tweeter, a mid-rangedriver, a low-range driver, and a subwoofer. In some embodiments, thezone player 200 can be statically or dynamically configured to playstereophonic audio, monaural audio, or both. In some embodiments, thezone player 200 may be dynamically configured to reproduce a subset offull-range sound, such as when the zone player 200 is grouped with otherzone players to play stereophonic audio, monaural audio, and/or surroundaudio or when the media content received by the zone player 200 is lessthan full-range.

FIG. 2B illustrates the zone player 202 that includes a built-inamplifier to power a set of detached speakers 210. A detached speakercan include, for example, any type of loudspeaker. The zone player 202may be configured to power one, two, or more separate loudspeakers. Thezone player 202 may be configured to communicate an audio signal (e.g.,right and left channel audio or more channels depending on itsconfiguration) to the set of detached speakers 210 via a wired path.

FIG. 2C illustrates the zone player 204 that does not include a built-inamplifier, but is configured to communicate an audio signal, receivedover a data network, to an audio (or “audio/video”) receiver 214 withbuilt-in amplification.

Referring back to FIG. 1 , in some embodiments, one, some, or all of thezone players 112-116 can retrieve audio directly from a source. Forexample, a particular zone player in a zone or zone group may beassigned to a playback queue (or “queue”). The playback queue maycontain information corresponding to zero or more audio items forplayback by the associated zone or zone group. The playback queue may bestored in memory on a zone player or some other designated device. Eachitem contained in the playback queue may comprise a uniform resourceidentifier (URI) or some other identifier that can be used by the zoneplayer(s) to seek out and/or retrieve the audio items from theidentified audio source(s). Depending on the item, the audio sourcemight be found on the Internet (e.g., the cloud), locally from anotherdevice over the data network 140 (e.g., the portable computing device130, described further below), from the controller 118, stored on thezone player itself, or from an audio source communicating directly tothe zone player. In some embodiments, the zone player can reproduce theaudio itself (e.g., play the audio), send the audio to another zoneplayer for reproduction, or both where the audio is reproduced by thezone player as well as one or more additional zone players (possibly insynchrony). In some embodiments, the zone player may play a first audiocontent (or alternatively, may not play the content at all), whilesending a second, different audio content to another zone player(s) forreproduction. To the user, each item in a playback queue may berepresented on an interface of a controller by an element such as atrack name, album name, radio station name, playlist, or other someother representation. A user can populate the playback queue with audioitems of interest. The user may also modify and clear the playbackqueue, if so desired.

By way of illustration, SONOS, Inc. of Santa Barbara, Californiapresently offers for sale zone players referred to as a “PLAY:5,”“PLAY:3,” “PLAYBAR,” “CONNECT:AMP,” “CONNECT,” and “SUB.” Any otherpast, present, and/or future zone players can additionally oralternatively be used to implement the zone players of exampleembodiments disclosed herein. Additionally, it is understood that a zoneplayer is not limited to the particular examples illustrated in FIGS.2A, 2B, and 2C or to the SONOS product offerings. For example, a zoneplayer may include a wired or wireless headphone. In yet anotherexample, a zone player might include a sound bar for television. In yetanother example, a zone player may include or interact with a dockingstation for an Apple iPod™ or similar device.

b. Example Controllers

FIG. 3 illustrates an example wireless controller 300 in a dockingstation 302. By way of illustration, the controller 300 may correspondto the controller 118 of FIG. 1 . The docking station 302, if providedor used, may provide power to the controller 300 and additionally maycharge a battery of the controller 300. In some embodiments, thecontroller 300 may be provided with a touch screen 304 that allows auser to interact through touch with the controller 300, for example, toretrieve and navigate a playlist of audio items, modify and/or clear theplayback queue of one or more zone players, control other operations ofone or more zone players, and provide overall control of the mediasystem of the POS display 110. In other embodiments, other inputmechanisms such as voice control may be used to interact with thecontroller 300. In certain embodiments, any number of controllers can beused to control the media system of the POS display 110. In someembodiments, there may be a limit set on the number of controllers thatcan control the media system of the POS display 110. The controllersmight be wireless like the wireless controller 300 or wired to the datanetwork 140.

In some embodiments, if more than one controller is used in the mediasystem of the POS display 110 of FIG. 1 , each controller may becoordinated to display common content, and may all be dynamicallyupdated to indicate changes made to the media system of the POS display110 from a single controller. Coordination can occur, for instance, by acontroller periodically requesting a state variable directly orindirectly from one or more of the zone players; the state variable mayprovide information about the media system of the POS display 110, suchas current zone group configuration, what is playing in one or morezones, volume levels, and other items of interest. The state variablemay be passed around on the data network 140 between zone players (andcontrollers, if so desired) as needed or as often as programmed.

In addition, a software application running on any portable computingdevice, such as an iPhone™, iPad™, Android™ powered phone or tablet, orany other smart phone or network-enabled device can be used as thecontroller 118 (e.g., the portable computing device 130). A softwareapplication running on a laptop or desktop personal computer (PC) orMac™ can also be used as the controller 118. Such controllers mayconnect to the media system of the POS display 110 through an interfacewith the data network 140, a zone player, a wireless router, or usingsome other configured connection path. Example controllers offered bySonos, Inc. of Santa Barbara, Calif. include a “Controller 200,” “SONOS®CONTROL,” “SONOS® Controller for iPhone™,” “ SONOS® Controller foriPad™,” “SONOS® Controller for Android™,” “SONOS® Controller for Mac™ orPC.”

c. Example Data Connection

The zone players 112-116 of FIG. 1 may be coupled directly or indirectlyto a data network, such as data network 140. The controller 118 may alsobe coupled directly or indirectly to the data network 140 or individualzone players. The data network 140 is represented by a cloud in FIG. 1 .While the data network 140 is shown in a single location, it isunderstood that such a network is distributed in and around the POSdisplay 110 and the portable computing device 130. Particularly, thedata network 140 can be a wired network, a wireless network, or acombination of both wired and wireless networks. In some embodiments,one or more of the zone players 112-116 may be wirelessly coupled to thedata network 140 based on a proprietary mesh network. In someembodiments, one or more of the zone players may be coupled to the datanetwork 140 using a centralized access point such as a wired or wirelessrouter. In some embodiments, one or more of the zone players 112-116 maybe coupled via a wire to the data network 140 using Ethernet or similartechnology. In addition to the one or more zone players 112-116connecting to the data network 140, the data network 140 can furtherallow access to a wide area network, such as the Internet.

In some embodiments, connecting any of the zone players 112-116, or someother connecting device, to a broadband router, may create the datanetwork 140. Other of the zone players 112-116 may then be added wiredor wirelessly to the data network 140. For example, a zone player (e.g.,any of the zone players 112-116) can be added to the media system of thePOS display 110 by simply pressing a button on the zone player itself(or perform some other action), which enables a connection to be made tothe data network 140. The broadband router can be connected to anInternet Service Provider (ISP), for example. The broadband router canbe used to form another data network within the example system 100,which can be used in other applications (e.g., web surfing). The datanetwork 140 can also be used in other applications, if so programmed. Anexample second network may implement SONOSNET™ protocol, developed bySONOS, Inc. of Santa Barbara. SONOSNET™ represents a secure,AES-encrypted, peer-to-peer wireless mesh network. Alternatively, incertain embodiments, the data network 140 is the same network, such as atraditional wired or wireless network, used for other applications in aretail or coffee shop environment, for example.

d. Example Zone Configurations

A particular zone may contain one or more zone players. For example,referring back to FIG. 1 , a first zone may contain the zone player 112and a second zone may contain the zone players 114-116. In someembodiments, a zone player may be assigned to a new or existing zone viathe controller 118 (or the computing device 130). As such, zones may becreated, combined with another zone, removed, and given a specific name(e.g., “Point-of-Sale Display Zone”) if so desired and programmed to doso with the controller 118 (or the computing device 130). Moreover, insome embodiments, zone configurations may be dynamically changed evenafter being configured using the controller 118 (or the computing device130) or some other mechanism.

In some embodiments, a “bonded zone” contains two or more zone players,such as the zone players 112 and 116, whereby the zone players 112 and116 may be configured to play the same audio source in synchrony. In oneexample, the zone players 112 and 116 may be paired to play two separatesounds in left and right channels, for example. In other words, thestereo effects of a sound can be reproduced or enhanced through the twozone players 112 and 116, one for the left sound and the other for theright sound. In another example two or more zone players can besonically consolidated to form a single, consolidated zone player. Aconsolidated zone player (though made up of multiple, separate devices)can be configured to process and reproduce sound differently than anunconsolidated zone player or zone players that are paired, because aconsolidated zone player has additional speaker drivers from which soundcan be passed. The consolidated zone player can further be paired with asingle zone player or yet another consolidated zone player. Eachplayback device of a consolidated playback device can be set in aconsolidated mode, for example.

In certain embodiments, paired or consolidated zone players (alsoreferred to as “bonded zone players”) can play audio in synchrony withother zone players in the same or different zones.

According to some embodiments, one can continue to do any of: group,consolidate, and pair zone players, for example, until a desiredconfiguration is complete. The actions of grouping, consolidation, andpairing are preferably performed through a control interface, such asusing the controller 118 or the computing device 130, and not byphysically connecting and re-connecting speaker wire, for example, toindividual, discrete speakers to create different configurations. Assuch, certain embodiments described herein provide a more flexible anddynamic platform through which sound reproduction can be offered to theend-user.

e. Example Audio Sources

In some embodiments, each zone can play from the same audio source asanother zone or each zone can play from a different audio source. Forexample, the zone players 112-116 may each belong to a separate zone,i.e., three zones may exist where each zone includes one zone player.Someone may listen to jazz music via the zone player 112, while someoneelse may listen to classical music via the zone player 116. Further, athird person may listen to the same jazz music via the zone player 114that is playing on the zone player 112. In some embodiments, the jazzmusic played via the zone players 112 and 114 may be played insynchrony. Synchronizing playback amongst zones allows for an individualto pass through zones while seamlessly (or substantially seamlessly)listening to the audio. Such a configuration may be referred to as asynchrony group. Further, zones may be put into a “party mode” such thatall associated zones will play audio in synchrony.

Sources of audio content that may be played by the zone players 112-116are numerous. In some embodiments, audio on a zone player itself may beaccessed and played. In some embodiments, audio on a controller may beaccessed via the data network 140 and played. In some embodiments, musicfrom a personal library stored on a computer or networked-attachedstorage (NAS) may be accessed via the data network 140 and played. Inother embodiments, music from a smartphone (e.g., the computing device130) may be accessed and played. In some embodiments, Internet radiostations, shows, and podcasts may be accessed via the data network 140and played (e.g., via the content provider server 152). Music or cloudservices that let a user stream and/or download music and audio contentmay be accessed via the data network 140 and played (e.g., via thecontent provider server 152). Further, music may be obtained fromtraditional sources, such as a turntable or CD player, via a line-inconnection to a zone player, for example. Audio content may also beaccessed using a different protocol, such as Airplay™ which is awireless technology by Apple, Inc., for example. Audio content receivedfrom one or more sources can be shared amongst the zone players 112-116via the data network 140 and/or the controller 118 or the portablecomputing device 130. The above-disclosed sources of audio content arereferred to herein as network-based audio information sources. However,network-based audio information sources are not limited thereto.

In some embodiments, the zone players 112-114 may be coupled to an audioinformation source such as a television. In some examples, thetelevision may be used as a source of audio for the zone player 112-114,while in other examples audio information from the television may beshared with any of the zone players 112-116 in the media system of thePOS display 110.

e. Example Servers

In some embodiments, one or more of the zone players 112-116, thecontroller 118, and/or the portable computing device 130 may communicatewith the local server 145, the media system server 150, and/or thecontent provider server 152. Each of the servers may include at leastone processor, memory, and a network interface, among other components.The network interface may facilitate data flow between a server andanother network device via the data network 140. Further, the variousservers may communicate with one another via the data network 140.

In one embodiment, the local server 145 may be associated with anenvironment (e.g., a retail store or a coffee shop), and the localserver 145 may store in memory data particular to the associatedenvironment. For example, the local server 145 may store account data,POS data, and/or POS-location data, among other data. The account datamay indicate one or more content provider subscriptions that theenvironment may receive media streams/downloads from. For example, aretail store may have a streaming media account (e.g., a Pandora®Internet Radio or Spotify® account), and the account data may indicateaccount login information and/or passwords used to obtain theseservices. The content provider server 152 may transmit these services tothe local server 145. The POS data may indicate one or more POS displaysthat the environment is currently displaying and the products and/orbrands of each POS display. The POS-location data may indicate locationsof each POS display within the environment. For example, thePOS-location data may indicate that a SONOS POS display is locatedsomewhere along aisle 23. In some embodiments, the local server 145 maystore in memory a software application that may be used to control amedia system of a POS display.

In certain embodiments, the media system server 150 may be associatedwith a POS display and/or a provider of products associated with a groupof POS displays. For example, the media system server 150 may beassociated with the POS display 110 and other POS displays that displaythe same or related products as the POS display 110. The media systemserver 150 may store in memory POS-location data, which may indicatewhere particular POS displays are located. In some embodiments, thePOS-location data may include GPS coordinates and/or geo-location data.Other location data types are also possible.

In some embodiments, the media system server 150 may store in memory asoftware application that may be downloaded over a data network (e.g.,the data network 140) by a portable computing device (e.g., the portablecomputing device 130). The software application may be used to control amedia system of a POS display (e.g., the media system of the POS display110). In other embodiments, the media system server 150 may store inmemory system identifiers associated with POS-display media systems. Thesystem identifiers may indicate one or more configuration variables thatmay allow a device to connect to a network of a POS-display. Forexample, the system identifiers may indicate individual media playbackdevices of a POS-display that the device may connect with. Other examplesystem identifiers are also possible.

III. Example Zone Players

Referring now to FIG. 4 , there is shown an example block diagram of azone player 400 in accordance with an embodiment. The zone player 400may include a network interface 402, a processor 408, a memory 410, anaudio processing component 412, one or more software modules 414, anaudio amplifier 416, and a speaker unit 418 coupled to the audioamplifier 416. FIG. 2A shows an example illustration of such a zoneplayer. Other types of zone players may not include the speaker unit 418(e.g., such as shown in FIG. 2B) or the audio amplifier 416 (e.g., suchas shown in FIG. 2C). Further, it is contemplated that the zone player400 can be integrated into another component. For example, the zoneplayer 400 could be constructed as part of a television, lighting, orsome other device for indoor or outdoor use.

In some embodiments, the network interface 402 facilitates a data flowbetween the zone player 400 and other devices on the data network 140.In some embodiments, in addition to getting audio from another zoneplayer or device on the data network 140, the zone player 400 may accessaudio directly from the audio source, such as over a wide area networkor on the local network. In some embodiments, the network interface 402can further handle the address part of each packet so that it gets tothe right destination or intercepts packets destined for the zone player400. Accordingly, in certain embodiments, each of the packets includesan Internet Protocol (IP)-based source address as well as an IP-baseddestination address.

In some embodiments, the network interface 402 can include one or bothof a wireless interface 404 and a wired interface 406. The wirelessinterface 404, also referred to as a radio frequency (RF) interface,provides network interface functions for the zone player 400 towirelessly communicate with other devices (e.g., other zone player(s),speaker(s), receiver(s), component(s) associated with the data network140, and so on) in accordance with a communication protocol (e.g., anywireless standard including IEEE 802.11a, 802.11b, 802.11g, 802.11n,802.11ac, 802.15, 4G mobile communication standard, and so on). Thewireless interface 404 may include one or more radios. To receivewireless signals and to provide the wireless signals to the wirelessinterface 404 and to transmit wireless signals, the zone player 400includes one or more antennas 420. The wired interface 406 providesnetwork interface functions for the zone player 400 to communicate overa wire with other devices in accordance with a communication protocol(e.g., IEEE 802.3). In some embodiments, a zone player may includemultiple wireless 404 interfaces. In some embodiments, a zone player mayinclude multiple wired 406 interfaces. In some embodiments, a zoneplayer may include both of the interfaces 404 and 406. In someembodiments, a zone player may include only the wireless interface 404or the wired interface 406.

In some embodiments, the processor 408 is a clock-driven electronicdevice that is configured to process input data according toinstructions stored in the memory 410. The memory 410 is data storagethat can be loaded with the one or more software modules 414, which canbe executed by the processor 408 to achieve certain tasks. In theillustrated embodiment, the memory 410 is a tangible machine-readablemedium storing instructions that can be executed by the processor 408.In some embodiments, a task might be for the zone player 400 to retrieveaudio data from another zone player or a device, such as the computingdevice 130, on a network (e.g., using a uniform resource locator (URL)or some other identifier). In some embodiments, a task may be for thezone player 400 to send audio data to another zone player or device(e.g., the computing device 130) on a network. In some embodiments, atask may be for the zone player 400 to synchronize playback of audiowith one or more additional zone players. In some embodiments, a taskmay be to pair the zone player 400 with one or more zone players tocreate a multi-channel audio environment. Additional or alternativetasks can be achieved via the one or more software modules 414 and theprocessor 408.

The audio processing component 412 can include one or moredigital-to-analog converters (DAC), an audio preprocessing component, anaudio enhancement component or a digital signal processor, and so on. Insome embodiments, the audio processing component 412 may be part of theprocessor 408. In some embodiments, the audio that is retrieved via thenetwork interface 402 may be processed and/or intentionally altered bythe audio processing component 412. Further, the audio processingcomponent 412 can produce analog audio signals. The processed analogaudio signals may then be provided to the audio amplifier 416 forplayback through the speaker unit 418. In addition, the audio processingcomponent 412 can include circuitry to process analog or digital signalsas inputs to play from the zone player 400, send to another zone playeron a network, or both play and send to another zone player on thenetwork. An example input includes a line-in connection (e.g., anauto-detecting 3.5 mm audio line-in connection).

The audio amplifier 416 is a device(s) that amplifies audio signals to alevel for driving one or more speakers of the speaker unit 418. The oneor more speakers 418 can include an individual transducer (e.g., a“driver”) or a complete speaker system that includes an enclosureincluding one or more drivers. A particular driver can be a subwoofer(e.g., for low frequencies), a mid-range driver (e.g., for middlefrequencies), and a tweeter (e.g., for high frequencies), for example.An enclosure can be sealed or ported, for example. Each transducer maybe driven by its own individual amplifier.

A commercial example, presently known as the PLAY:5™, is a zone playerwith a built-in amplifier and speakers that is capable of retrievingaudio directly from the source, such as on the Internet or on the localnetwork, for example. In particular, the PLAY:5™ is a five-amp,five-driver speaker system that includes two tweeters, two mid-rangedrivers, and one woofer. When playing audio content via the PLAY:5, theleft audio data of a track is sent out of the left tweeter and leftmid-range driver, the right audio data of a track is sent out of theright tweeter and the right mid-range driver, and mono bass is sent outof the subwoofer. Further, both mid-range drivers and both tweeters havethe same equalization (or substantially the same equalization). That is,they are both sent the same frequencies but from different channels ofaudio. Audio from Internet radio stations, online music and videoservices, downloaded music, analog audio inputs, television, DVD, and soon, can be played from the PLAY:5™

IV. Example Controller

Referring now to FIG. 5 , there is shown an example block diagram for acontroller 500, which can correspond to the controller 118 in FIG. 1 .The controller 500 can be used to facilitate the control of multi-mediaapplications, automation and others in a system. In particular, thecontroller 500 may be configured to facilitate a selection of aplurality of audio sources available on the data network 140 and enablecontrol of one or more zone players (e.g., the zone players 112-116 inFIG. 1 ) through a wireless or wired network interface 508. According toone embodiment, the wireless communications may be based on an industrystandard (e.g., infrared, radio, wireless standards including IEEE802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.15, 4G mobilecommunication standard, and so on). Further, when a particular audio isbeing accessed via the controller 500 or being played via a zone player,a picture (e.g., album art) or any other data, associated with the audioand/or audio source can be transmitted from a zone player or otherelectronic device to the controller 500 for display.

The controller 500 may be provided with a screen 502 and an inputinterface 514 that may allow a user to interact with the controller 500,for example, to navigate a playlist of many multimedia items and tocontrol operations of one or more zone players. The screen 502 on thecontroller 500 can be an LCD screen, for example. The screen 500communicates with and is commanded by a screen driver 504 that iscontrolled by a microcontroller (e.g., a processor) 506. The controllermemory 510 can be loaded with one or more application modules 512 thatcan be executed by the microcontroller 506 with or without a user inputvia the user interface 514 to achieve certain tasks. In someembodiments, the application module 512 may be configured to facilitategrouping a number of selected zone players into a zone group tofacilitate synchronized playback amongst the zone players in the zonegroup. In some embodiments, the application module 512 may be configuredto control the audio sounds (e.g., volume) of the zone players in a zonegroup. In operation, when the microcontroller 506 executes one or moreof the application modules 512, the screen driver 504 may generatecontrol signals to drive the screen 502 to display an applicationspecific user interface accordingly.

The controller 500 includes a network interface 508 that may facilitatewired or wireless communication with a zone player. In some embodiments,the commands such as volume control and audio playback synchronizationmay be sent via the network interface 508. In some embodiments, a savedzone group configuration may be transmitted between a zone player and acontroller via the network interface 508. The controller 500 can controlone or more zone players, such as the zone players 112-116 of FIG. 1 .There can be more than one controller for a particular system, and eachcontroller may share common information with another controller, orretrieve the common information from a zone player, if such a zoneplayer stores configuration data (e.g., such as a state variable).Further, a controller can be integrated into a zone player.

It should be noted that other network-enabled devices such as aniPhone™, iPad™ or any other smartphone (e.g., the portable computingdevice 130) or network-enabled device (e.g., a networked computer suchas a PC or Mac™) can also be used as a controller to interact or controlzone players in a particular environment. In some embodiments, asoftware application or upgrade can be downloaded onto a network-enableddevice to perform the functions described herein. It should beunderstood that the portable computing device 130 described earlier inconnection with FIG. 1 may include all or some of the same components asthe controller 500. Further, it should be understood that the portablecomputing device 130 may be configured to perform all or some of thesame operations as the controller 500. For example, the portablecomputing device 130 may be configured to facilitate a selection of anumber of audio sources available on the data network 140 and enablecontrol of one or more of the zone players 112-116.

In certain embodiments, a user can create a zone group (also referred toas a bonded zone) including at least two zone players from thecontroller 500. The zone players in the zone group can play audio in asynchronized fashion, such that all of the zone players in the zonegroup playback an identical audio source or a list of identical audiosources in a synchronized manner such that no (or substantially no)audible delays or hiccups are to be heard. Similarly, in someembodiments, when a user increases the audio volume of the group fromthe controller 500, the signals or data of increasing the audio volumefor the group are sent to one of the zone players and causes other zoneplayers in the group to be increased together in volume.

A user via the controller 500 can group zone players into a zone groupby activating a “Link Zones” or “Add Zone” soft button, or de-grouping azone group by activating an “Unlink Zones” or “Drop Zone” button. Forexample, one mechanism for ‘joining’ zone players together for audioplayback is to link a number of zone players together to form a group.To link a number of zone players together, a user can manually link eachzone player or zone one after the other. For example, assume that thereis a multi-zone system that includes six zones, each including at leastone zone player. In certain embodiments, a user can link any number ofthe six zone players, for example, by starting with a single zone andthen manually linking each zone to that zone.

In certain embodiments, a set of zones can be dynamically linkedtogether using a command to create a zone scene or theme (subsequent tofirst creating the zone scene). For instance, a “Retail Store Opens”zone scene command can link multiple zones together in one action.Without this single command, the user would manually and individuallylink each zone. The single command may include a mouse click, a doublemouse click, a button press, a gesture, or some other programmed orlearned action. Other kinds of zone scenes can be programmed or learnedby the system over time.

In certain embodiments, a zone scene can be triggered based on time(e.g., an alarm clock function). For instance, a zone scene can be setto apply at 8:00 am. The system can link appropriate zonesautomatically, set specific music to play, and then stop the music aftera defined duration and revert the zones to their prior configuration.Although any particular zone can be triggered to an “On” or “Off” statebased on time, for example, a zone scene enables any zone(s) linked tothe scene to play a predefined audio (e.g., a favorable song, apredefined playlist) at a specific time and/or for a specific duration.If, for any reason, the scheduled music failed to be played (e.g., anempty playlist, no connection to a share, failed Universal Plug and Play(UPnP), no Internet connection for an Internet Radio station, and soon), a backup buzzer can be programmed to sound. The buzzer can includea sound file that is stored in a zone player, for example.

V. Example Playback Network

Particular examples are now provided in connection with the POS display110 of FIG. 1 to describe, for purposes of illustration, certainembodiments to provide and facilitate connection to the media system ofthe POS display 110. FIG. 1 shows that there are three zone players 112,114 and 116 and a controller 118 that form a network branch that is alsoreferred to as the playback network 120. The playback network 120 may bewireless, wired, or a combination of wired and wireless technologies.The playback network 120 may be an “ad-hoc” network. In general, an“ad-hoc” (or “spontaneous”) network is a local area network or othersmall network in which there is generally no one access point for alltraffic. With the established playback network 120, the devices 112-118can all communicate with each other in a “peer-to-peer” style ofcommunication, for example. Furthermore, devices (e.g., the portablecomputing device 130) may join and/or leave from the playback network120, and the playback network 120 will automatically reconfigure itselfwithout needing the user to reconfigure the playback network 120. Whilean ad-hoc network is discussed, it is understood that the playbacknetwork 120 may be based on a type of network that is completely orpartially different from an ad-hoc network.

Using the playback network 120, the devices 112-118 can share orexchange one or more audio sources and be dynamically grouped (orungrouped) to play the same or different audio sources. For example, thezone players 112 and 114 may be grouped to playback one piece of music,and at the same time, the zone player 116 may playback another piece ofmusic. In other words, the devices 112-118, as shown in FIG. 1 , form aGROUPING that distributes audio and/or reproduces sound. As used herein,the term GROUPING is used to represent a collection of networked devicesthat are cooperating to provide an application or service. playback

In certain embodiments, a GROUPING identifier (GID) is a short string oran identifier that is computer-generated to help ensure that it isunique. Accordingly, the layback network 120 can be characterized by aunique GID and a unique set of configuration variables or parameters,such as channels (e.g., respective frequency bands), a service setidentifier (SSID) (a sequence of alphanumeric characters as a name of awireless network), and WEP keys (wired equivalent privacy) or othersecurity keys. In certain embodiments, a SSID is set to be the same asthe GID.

In certain embodiments, each GROUPING may include two types of networknodes: a control point (CP) and a zone player (ZP). The CP controls anoverall network setup process and sequencing, including an automaticgeneration of required network parameters (e.g., security keys). In anembodiment, the CP also provides the user with a GROUPING configurationuser interface. The CP function can be provided by a computer running aCP application module, or by a handheld controller (e.g., the controller300) also running a CP application module, for example. The ZP is anyother device on the network that is placed to participate in theautomatic configuration process. In certain embodiments, the ZP, as anotation used herein, may include the controller 300 or a computingdevice, for example. In some embodiments, the functionality, or certainparts of the functionality, in both the CP and the ZP may be combined ata single node (e.g., a ZP contains a CP or vice-versa).

In certain embodiments, a GROUPING configuration may involve multipleCPs and ZPs that rendezvous and establish a known configuration suchthat they can use a standard networking protocol (e.g., IP over Wired orWireless Ethernet) for communication. In an embodiment, two types ofnetworks/protocols may be employed: Ethernet 802.3 and Wireless 802.11g.Interconnections between a CP and a ZP can use either of thenetworks/protocols. A device in the system as a member of a GROUPING canconnect to both networks simultaneously.

In an environment that has both networks in use, it is assumed that atleast one device in a system is connected to both as a bridging device,thus providing bridging services between wired/wireless networks forothers. The zone player 112 in FIG. 1 could be connected to bothnetworks, for example. The connectivity to the networks may be based onEthernet and/or Wireless, while the connectivity to other devices114-118 may be based on Wireless and Ethernet if so desired.

It is understood, however, that in some embodiments each zone player112-116 may access the Internet when retrieving media from the cloud(e.g., the Internet) via the bridging device. For example, the zoneplayer 112 may contain a uniform resource locator (URL) that specifiesan address to a particular audio track in the cloud. Using the URL, thezone player 112 may retrieve the audio track from the cloud, andultimately play the audio out of one or more of the other zone players.

In some embodiments, a device (e.g., the computing device 130) may joinan established GROUPING. For example, in reference to FIG. 1 , the mediasystem of the POS display 110 may constitute a GROUPING formed byGROUPING members: the zone players 112-116 and the controller 118. Theportable computing device 130 may include a software application thatmay be configured to control the GROUPING. The software application onthe portable computing device 130 may join the POS display 110 (e.g.,the portable computing device 130 may join the GROUPING formed by themedia system of the POS display) according to the example proceduresdiscussed below.

The device may receive a command to join the GROUPING (e.g., from a userinput). Upon receiving a command to join the device (e.g., the portablecomputing device 130) to the GROUPING, the device may execute anembedded module that may be configured to establish a communication pathwith a member device (e.g., any of the zone players 112-116 or thecontroller 118). The communication path may facilitate an automaticconfiguration of the device via the member device. This communicationpath may operate over wireless and/or wired (e.g., Ethernet) protocols.In operation, the communication path does not cause negative effects onother devices in the vicinity and may reach all other members of theGROUPING, if there are any. It should also be noted that thecommunication path does not have to be direct between the device and themember device. It may be bridged by one or more other devices. Becausethe communication path is only used for initial device configuration, itdoes not require significant performance or sophisticated functionality.There are at least two elements to establish the communication path:channel selection and packet exchange.

Generally speaking, the selection of an appropriate (RF) transmissionchannel or simply channel is primarily an exercise in two constraints:finding a channel that is quiet from a protocol (e.g., 802.11)viewpoint, i.e., minimal conflicting wireless traffic, and finding achannel that is quiet from an RF viewpoint, i.e., minimal noise fromother signals. Both of these tests may be applied because typically acoffee shop/retail environment may have other RF (e.g., 2.4 GHz) trafficor potentially other wireless access points. It is generally desirableto use a channel that is free from other RF interference. In any case,it is always desirable to avoid other wireless traffic.

Channel selection may be accomplished with a scanning technique, namelythe device (e.g., the computing device 130) may listen on each channelfor a period of time, looking for the presence of wireless beacons andother RF signals. In one embodiment, member devices that are configured(e.g., the zone players 112-116 and the controller 118) may have apreferred channel for the GROUPING, while the device (e.g., the portablecomputing device 130 and other devices that are not configured) may havea pre-defined (default) channel or channels that they rendezvous on. Forexample, 802.11 b/g channel 1 could be pre-configured as the defaultchannel. Alternatively, multiple channels, with a well-known frequencyhopping sequence, could be used by the device (this would require anaperiodic frequency change interval).

Many hardware configurations may only support reception/transmission ona single channel at a given time. Also there are configured andnon-configured devices that may use different channels for the bootstrapconfiguration and standard network operations (post-configurationcommunications). According to one embodiment, it may be necessary toforcibly put the device (e.g., the portable computing device 130) in a“configuration” mode, whereby the device uses the appropriate channelsfor communication.

To enable communication between devices that are not part of theGROUPING, a packet exchange network infrastructure may be developed.Probing messages may be sent in over wireless and/or Ethernet networks,reaching any connected devices. Devices that are already in the GROUPING(e.g., the zone players 112-116 and the controller 118) constitute anetwork infrastructure that may be used to exchange unicast andmulticast/broadcast network frames between the devices. The portablecomputing device 130, or any other device that is not yet a member ofthe GROUPING may have more limited networking capability and may, forexample, only receive data from devices to which it is directlyconnected to and unencrypted messages broadcast to all wireless networksoperating in a particular channel of the RF spectrum.

In general, an IP address of the portable computing device 130, oranother device that wishes to join the GROUPING, may not be known to anymembers of the GROUPING. In some instances, the portable computingdevice 130 may not have an IP address at all, or it may have anautomatically assigned IP address that is inaccessible to other deviceswith IP addresses respectively assigned by a DHCP server. To allow theportable computing device 130 and other devices that are not members ofthe GROUPING to join the GROUPING, a transport may be constructed thatmay get data one “hop” beyond the GROUPING network infrastructure.

In one embodiment, packets of data may be broadcast among the memberdevices of the GROUPING. The packets of data may comprise a mixture of“probe” datagrams and standard IP broadcast. For example, the 802.11“probe” datagrams are used for the inherent ability to cross wirelessnetwork boundaries. In other words, the “probe” datagrams may bereceived by all listeners (e.g., the portable computing device 130) onthe channel, even those that are not configured with an SSID, becausethey are sent to the broadcast BSS (e.g., FF:FF:FF:FF:FF:FF) to whichall devices may be configured to listen. A standard IP broadcast may beused on the GROUPING network infrastructure to enable a PC-basedcontroller to participate while running with standard user privileges(which allow access only to IP-based network services). Used together asdescribed below, the combination of the “probe” datagrams and IPbroadcast provides for a broadcast datagram transport that allows evendevices that have not had any networking parameters configured tocommunicate.

In general, the probe datagrams may comprise a number of elements tofacilitate the configuration of other devices (e.g., the portablecomputing device 130) to join the GROUPING. In one embodiment, each ofthe elements may carry up to 255 bytes of data. An element may containdata payload for each message used by the bootstrap procedure to inviteothers to join the GROUPING. This element may be repeated as many timesas necessary to carry the complete message. In one embodiment, the IPbroadcast datagram may contain the same data payload as the normal IPdata payload.

Messages relating to the bootstrap procedure may be forwarded beyond theboundaries of the existing GROUPING network infrastructure (e.g., theplayback network 120). Similarly, messages originating outside of theGROUPING network infrastructure may be forwarded into theinfrastructure. This forwarding procedure may be accomplished in a mixedwireless/wired network environment without introducing a broadcaststorm. A broadcast storm is a state in which a message that has beenbroadcast across a network results in more responses than necessary, andeach response results in even more responses in a snowball effect,subsequently resulting in a network meltdown. In one embodiment, thenetwork may be configured to prevent such a broadcast storm or anyillegal broadcast messages. To accomplish this, two flags may beincluded in the message body, for example, “SENT_AS_PROBE” and“SENT_AS_IP BROADCAST”. When a member device receives a “probe” message,assumed using “Sonos Netstart” SSID (or the broadcast BSS, as with allprobe requests), it may forward the message as an IP broadcast message(after setting the “SENT AS_IP BROADCAST” flag) if the SENT_AS_IPBROADCAST flag is not already set. Similarly, when a member devicereceives an IP broadcast with a UDP payload address to an appropriateport (e.g., port number 6969), it may forward the message as a “probe”datagram (after setting the “SENT AS_PROBE” flag) if that flag is notalready set. This may allow messages related to the packet exchange bothto enter and to exit the GROUPING network infrastructure without causinga broadcast storm.

Using this method of broadcast communication, packets may be sentbetween any member of the GROUPING and a device (e.g., the portablecomputing device 130) to join the GROUPING on wireless and/or Ethernetnetworks. The device to join the GROUPING may be brand new andpreviously configured with a different network (e.g., the portablecomputing device 130 with a stale configuration in a differentGROUPING). In addition, if used sparingly, these broadcast messages maynot interfere with the normal operation of the network or attacheddevices. As a result, a communication path on an agreed channel may beestablished between two devices.

VI. Example Methods

FIG. 6 is a flowchart depicting an example method 600 for discovering aPOS display and receiving personalized media playback at the discoveredPOS display. Method 600 is described by way of example as being carriedout by a portable computing device. For clarity, the method 600 will bedescribed herein with reference to FIG. 1 being carried out by theportable computing device 130. However, it should be understood that theexample methods described herein may be carried out by other portablecomputing devices and/or systems.

Furthermore, those skilled in the art will understand that the flowchartdescribed herein depicts functionality and operation of certainimplementations of example embodiments. In this regard, each block ofthe flowchart may represent a module, a segment, or a portion of programcode, which includes one or more instructions executable by a processorfor implementing specific logical functions or steps in the process. Theprogram code may be stored on any type of computer readable medium,e.g., such as a storage device including a disk or hard drive. Inaddition, each block may represent circuitry that is wired to performthe specific logical functions in the process. Alternativeimplementations are included within the scope of the example embodimentsof the present application in which functions may be executed out oforder from that shown or discussed, including substantially concurrentor in reverse order, depending on the functionality involved, as wouldbe understood by those skilled in the art.

As shown in block 601, the method 600 may involve a portable computingdevice discovering a POS display, where the POS display includes atleast one media playback device. For example, the portable computingdevice 130 may discover the POS display 110 that includes the zoneplayers 112-116.

In one embodiment, the portable computing device discovering the POSdisplay may involve the portable computing device receiving anotification regarding the POS display. In some embodiments, thenotification may indicate a location of the POS display. In otherembodiments, the notification may further include a hyperlink to asoftware application, where the software application may be configuredto control the POS display.

For example, a user with the portable computing device 130 may walk intoa retail store where the example system 100 is implemented. The portablecomputing device 130 may connect to the data network 140 (e.g., via anaccess point such as a router), and the portable computing device 130may receive a notification (e.g., from the local server 145). Thenotification may include textual data indicating the location of the POSdisplay 110. In other instances, the notification may also include ahyperlink that may direct the portable computing device 130 to anelectronic address of a software application (e.g., a softwareapplication stored on the media system server 150). The softwareapplication may be configured to control the POS display. Other examplenotifications may exist.

In some embodiments, the POS display may be associated with displaybarcode data that indicates an electronic address of a softwareapplication, where the software application may be configured to controlthe POS display. The display barcode data may or may not be part of thePOS display. In one example, the display barcode data may be in physicalproximity to the POS display. In other examples, the display barcodedata may be located within the same environment as the POS display. Inyet other examples, the display barcode data and the POS display may belocated in separate environments. Other examples are also possible. Thedisplay barcode data may be a machine-readable barcode or a scannable QRcode, among other examples.

In some embodiments, discovering the POS display may involve theportable computing device receiving the electronic address data via ascanning component of the portable computing device (e.g., a smartphonecamera). For example, a customer may use his/her smartphone (e.g., theportable computing device 130) to scan a POS-display QR code, and thesmartphone may then receive display barcode data indicating theelectronic address of the software application, where the softwareapplication may be configured to control the POS display 110.

In some embodiments, discovering the POS display may involve theportable computing device receiving location data that indicates alocation of the POS display. In some instances, the location data may beincluded in a notification received by the portable computing device. Inother embodiments, the location data may be independent of anotification. The portable computing device may receive the locationdata over a data network from a networked device. For example, theportable computing device 130 may receive the location data from thelocal server 145, the media system server 150, or a third-party server(not pictured). In some embodiments, the portable computing device 130may receive the location data from a POS-display barcode.

In one embodiment, the location data may include GPS data and/orgeo-location data that indicates a location of the POS display. In otherembodiments, the location data may include textual data that indicates alocation of the POS display in known or easily discernible directions.For example, in the retail store environment, the data network 140 maybe public a wireless network provided by the retail store to customers.The local server 145 may contain a database of POS displays and theircorresponding locations within the retail store. When a customerconnects his/her smartphone (e.g., the portable computing device 130) tothe retail store wireless network (e.g., the data network 140), thelocal server 145 may transmit the location data to the portablecomputing device 130. The location data may display to the customer onhis/her smartphone (e.g., once output at an output component of theportable computing device 130), “Go test-drive the point-of-sale displayat aisle 23.”

In other embodiments, discovering the POS display may involve theportable computing device transmitting device-location data indicating acurrent location of the portable computing device to a server (e.g., themedia system server 150 or a third party server) over a data network.The portable computing device may then receive from the server locationdata of a POS display determined to be in close proximity to theportable computing device. For example, a user may have locationservices enabled on his/her smartphone, which may transmit a currentlocation of the smartphone to a server (e.g., the media system server150) via a data network (e.g., a wireless network or a cellular network)at predetermined intervals or continuously while the location servicesare enabled. In one embodiment, the user may have installed athin-client application on his/her smartphone from the media systemserver 150 or a third-party that uses a current location of a user'ssmartphone to identify “near” POS displays. For example, a user may bewalking down a street and come within a predefined proximity of anenvironment (e.g., a coffee shop or a retail store) that has a POSdisplay within. Subsequently, the user may receive at his/her smartphonelocation data related to the POS display located within the environment.The location data may be transmitted from the media system server 150via, for example, a cellular network. In response to the location data,an output component of the smartphone may prompt the user “Come to thecoffee shop at 123 Sonos Avenue and see the POS display”, among otherpossible prompts.

In some embodiments, after the portable computing device receives thelocation data, the portable computing device may cause an outputcomponent to provide an indication of the location of the POS display.In one embodiment, the portable computing device 130 may cause agraphical display to provide a visual indication of the location of thePOS display. For example, the portable computing device 130 may outputan image of a map with a mark on the map identifying the location of thePOS display. In another example, the portable computing device 130 mayoutput the textual message: “Go to the electronics department totest-drive the POS display”, among other example messages. In otherembodiments, the portable computing device 130 may include a speaker andmay cause the speaker to output an audible indication of the location ofthe POS display. For example, the portable computing device 130 may playa recording at the speaker that outputs in a recorded voice: “Go to theelectronics department to see the POS display”, among other examplerecordings.

At block 602, the method 600 may involve the portable computing devicereceiving, over a wireless network, a software application and a systemidentifier. For example, in one embodiment, the portable computingdevice 130 may receive via the data network 140 a software applicationand a system identifier from the media system server 150. In anotherexample, the portable computing device 130 may receive the softwareapplication and the system identifier from the POS display 110 (e.g.,from one of the zone players 112-116 or the controller 118). The POSdisplay 110 may have received the software application and/or the systemidentifier from the local server 145 and/or the media system server 150.In other embodiments, the portable computing device may receive thesoftware application from a first device and the system identifier froma second device. For example, the portable computing device 130 mayreceive the software application from the media system server 150 andreceive the system identifier from the POS display 110. Otheralternatives are also possible.

In one embodiment, the system identifier may be used to automaticallyconfigure the software application to control the at least one mediaplayback device at the discovered POS display. The system identifier isa globally unique identifier that may correspond to one or moreconfiguration variables that cause the software application on theportable computing device to be configured to control the media systemof the POS display. The system identifier may correspond to a globallyunique GID and/or a unique set of configuration variables or parametersof the POS-display, such as channels (e.g., respective frequency bands),SSID and WEP keys or other security keys. For example, the systemidentifier may correspond to identifiers unique to the playback network120 that may cause the computing device 130 to connect to the mediasystem of the POS-display 110. In other embodiments, the systemidentifier may correspond to identifiers unique to the at least onemedia playback device.

In some embodiments, the software application may be configured to causethe portable computing device to carry out the same or similaroperations and functions as the controller 500. For example, thesoftware application received by the portable computing device may bethe same as or similar to the software application discussed above inreference to FIG. 5 .

At block 603, the method 600 may involve joining the softwareapplication on the portable computing device to the POS display usingthe system identifier of the POS display. Joining the softwareapplication on the portable computing device to the POS display maycause the portable computing device to be enabled to control the POSdisplay via the software application. In some embodiments, joining thesoftware application on the portable computing device to the POS displaymay involve the portable computing device joining the playback networkof the POS display. For example, joining the software application on theportable computing device 130 to the POS display 110 may involve theportable computing device 130 joining the playback network 120.

In one embodiment, the portable computing device 130 may join theplayback network 120 in the same or similar manner as a device joining aplayback network as discussed above. In some embodiments, for example,the software application on the portable computing device 130 may usethe system identifier of the POS display 110 to join the portablecomputing device 130 to the playback network 120. In other embodiments,the portable computing device may join the playback network byconnecting directly with a zone player. For example, the portablecomputing device 130 may join the playback network 120 by connectingdirectly to one of the zone players 112-116 using, for example,Bluetooth, Wifi Direct, or a proprietary protocol, among otherprotocols.

In some embodiments, joining the software application on the portablecomputing device to the POS display may involve the portable computingdevice connecting to a data network (that the POS display is alsoconnected to) and launching the software application on the portablecomputing device. For example, after the portable computing device 130and the POS display 110 are both connected to the data network 140, thesoftware application on the portable computing device 130 may belaunched, and the portable computing device 130 may then control the POSdisplay. The software application may be launched in response toreceiving a user input at the portable computing device that indicates adesire to launch the software application. In some embodiments, thesoftware application may not be launched until after the systemidentifier configures the software application to control the at leastone media playback device at the discovered POS display.

In one embodiment, joining the software application on the portablecomputing device to the POS display may involve the portable computingdevice connecting to a data network (that the POS display is alsoconnected to) and the portable computing device detecting that the POSdisplay is the only POS display connected to the data network.

In other embodiments, joining the software application on the portablecomputing device to the POS display may involve the software applicationcausing the portable computing device to recognize one or more GIDsand/or SSIDs and the portable computing device detecting a GID and/orSSID from the one or more GIDs and/or SSIDs transmitted from the POSdisplay. In one embodiment, after detecting the GID and/or SID, thesoftware application on the portable computing device may automaticallyjoin to the POS display if the software application is not yetassociated with a GROUPING. In one embodiment, the joining proceduresmay require a user input indicating a desire to join the POS display.

In some embodiments, after joining the software application on theportable computing device to the POS display, the portable computingdevice may receive display data from the POS display. The display datamay indicate an identifier for each of the playback devices (e.g., thezone players 112-116), an identifier for each controller (e.g., thecontroller 118 and/or another portable computing device acting as acontroller), audio content available for playback by the at least oneplayback device, existing zone groups, existing synchrony groups,existing zone scenes, what audio is currently playing in one or morezones and/or at one or more zone players, and volume levels, among otherdata. In one embodiment, the controller may display a visual indicationcorresponding to the display data.

In one embodiment, after joining the software application on theportable computing device to the POS display, the method 600 may furtherinvolve indexing audio content on the portable computing device, wherethe audio content may be played by a media playback device subsequent toindexing. Indexing audio content may involve identifying audio content(e.g., audio files, audio applications, and/or audio content provideraccount information) stored on a device or otherwise associated with thedevice, and compiling a database of the identified audio content. Thedatabase may include file locations of the audio content, electronicaddresses of the audio content, track titles, artist/band names, andaudio content provider data, among other possible data. The indexing mayinvolve a standard and/or proprietary protocol for accessing the audiocontent on the portable computing device (e.g., the SMB protocol, amongother protocols). In some embodiments, the indexing may occur at theportable computing device. In other embodiments, the indexing may occurat the POS display (e.g., at one or more media playback devices and/orat a controller).

In one embodiment, the software application may cause the portablecomputing device 130 to index audio content on the portable computingdevice 130. The audio content may include local audio files located onthe computing device 130 and/or streaming media service accountsassociated with the computing device 130. In some embodiments, thecomputing device 130 may already index audio content without need forany action by the software application.

In other embodiments, after indexing, the portable computing device 130may transmit indexed audio data to the POS display 110. The zone players112-116 may then access the audio indicated by the indexed audio data.For example, any of the zone players 112-116 may access a local audiofile located on the computing device 130 or may use the accountinformation associated with the portable computing device 130 to obtainstreaming media from the content provider server 152. Other examples arealso possible.

In some embodiments, after indexing, the software application on theportable computing device may cause an output component of the portablecomputing device to output a customized view for the user based on theindexed audio data. The customized view may include indexed audiocontent from the portable computing device, indexed audio content froman audio service (e.g., the content provider server 152) associated withan environment (e.g., a retail or a coffee shop where the POS display islocated) which may be determined based on the audio content from theportable computing device, supported music services, which may bedetermined by the software application automatically detecting musicservice applications on the portable computing device, and “Play To”capabilities from supported applications and/or devices. Other examplesare also possible.

In other embodiments, a second portable computing device may also jointhe playback network 120 and access the audio data indicated by theindexed audio data of the portable computing device 130. Similarly, theportable computing device 130 may access the audio data of the secondportable computing device. In some embodiments, a user of the portablecomputing device may use the software application to select whetherother portable computing devices may access the audio data associatedwith the user's portable computing device.

In some embodiments, after joining the software application on theportable computing device to the POS display, the software applicationmay cause the portable computing device to transmit registration data toa server associated with the POS display. The registration data mayindicate a user identifier (e.g., a user name and/or cell phone numberassociated with the portable computing device), a location of the POSdisplay, a time stamp of when the portable computing device joined thePOS display, and a previous GROUPING(s) that the portable computingdevice belonged to, if any, among other examples. For example, theportable computing device 130 may transmit registration data indicatingthat the portable computing device 130 is associated with a GROUPING ofthe POS display to the media system server 150 via the data network 130.In one embodiment, user permission may be required before theregistration data is transmitted. In other embodiments, the registrationdata is transmitted automatically.

As shown in block 604, the method 600 may involve the portable computingdevice sending via the configured software application one or morecommands to control the at least one media playback device. For example,the portable computing device 130 may use the configured softwareapplication to send the zone player 116 (and/or other zone players) acommand to play audio. In response, the zone player 116 may locate theaudio, obtain an audio stream from the audio source, and output theaudio at the zone player 116. In some embodiments, the audio source maybe the content provider server 152 or the portable computing device 130,among other sources.

In some embodiments, the configured software application may facilitateregistering a streaming service identified on the portable computingdevice to the POS display. For example, the software application at theportable computing device 130 may register one or more of the zoneplayers 112-116 to receive a streaming service from the content providerserver 152. In one embodiment, the streaming service may be registeredto a generic or retail user account. Account data indicating the genericor retail user account may be stored at the local server 145. In otherembodiments, the streaming service may be registered to the user'saccount, and the user's music library may be added to the media systemof the POS display. The user's account data may be stored on theportable computing device.

In some embodiments, the method 600 may further involve the portablecomputing device terminating access to the POS display after apredefined duration. For example, the software application may cause theportable computing device 130 to terminate the access to the playbacknetwork 120 after the lapse of a predefined amount of time (e.g., 1hour, 1 day, etc.). In other embodiments, access between the portablecomputing device and the POS display may terminate based on a user inputat the portable computing device that indicates a desire to terminatethe connection with the POS display. In some embodiments, the access mayterminate based on a predefined proximity between the portable computingdevice and the POS display. For example, once the portable computingdevice 130 is a predefined distance away from the POS display 110, theconnection may be terminated. In other embodiments, the access mayterminate based on a measure of activity or inactivity (e.g., 10minutes) at the portable computing device. In one embodiment, the accessmay terminate when the portable computing device loses connection to adata network (e.g., the data network 140). Other examples forterminating access to the POS display are also possible.

In some embodiments, after terminating access to the POS display, theportable computing device may no longer control the POS display.Additionally, the playback devices of the POS display may no longeraccess audio stored on the portable computing device and/or the playbackdevices may not use streaming media accounts associated with theportable computing device. For example, in one embodiment, afterterminating access to the POS display, the software application on theportable computing device 130 may cause the POS display 110 to removeany indexed audio data associated with the portable computing device130.

In some embodiments, the portable computing device may control the POSdisplay without having to perform all of method 600. For example, in oneembodiment, the portable computing device may have the softwareapplication installed on the portable computing device prior todiscovering a POS display. In such a scenario, the portable computingdevice may discover the POS display and upon discovering the POSdisplay, the portable computing device may receive data such that thesoftware application can automatically control the POS display.

For instance, in one embodiment, a portable computing device may alreadyhave the software application, and a user may have allowed the softwareapplication to use “location services.” The software application mayprovide a media system server current location data of the portablecomputing device via, for example, a cellular network or a wirelessnetwork. The current location data may indicate where the portablecomputing device is currently located (e.g., GPS coordinates orgeo-location data). The media system server may identify POS displaysnearby the current location of the portable computing device. When theportable computing device is within a predefined proximity of thelocation of a POS display, the media system server may send anotification to the portable computing device indicating that a POSdisplay is nearby. Further, the media system server may provide thesoftware application on the portable computing device a systemidentifier for a media system of the nearby POS display and network data(e.g., SSID, GID, channel data, etc.) such that the software applicationcan automatically control the POS display. The software application onthe portable computing device may automatically control the media systemonce the portable computing device connects to a network of theenvironment (e.g., a retail store wireless network) that the mediasystem is also connected to.

In another embodiment where the portable computing device already hasthe software application installed, the software application may includea list of access point SSIDs, which may be associated with POS displays.In some embodiments, the software application may retrieve the list ofaccess point SSIDs from a media system server via a data network (e.g.,a wireless network or a cellular network). A POS display may transmit anSSID that is included in the list of access point SSIDs. The portablecomputing device may receive the SSID, and in response, the softwareapplication may cause the portable computing device to communicate withthe POS display and exchange credentials. In one embodiment, once thecredentials are confirmed, the portable computing device and the POSdisplay may transition to a second SSID, which may allow the portablecomputing device to control the POS display.

In other embodiments, the method 600 may further involve using thesoftware application to play audio on the portable computing device. Forexample, the portable computing device 130 may send a command to thezone player 112 to play an audio track (or an audio stream from thecontent provider 152). The audio track may be stored on the portablecomputing device 130. The zone player 112 may begin outputting the audiotrack. Subsequently, a user of the portable computing device 130 maydecide to walk away from the POS display 110, while the zone player 112is still playing the audio track. The software application may cause theportable computing device 130 to continue playing the audio track at theportable computing device 130. In some embodiments, the portablecomputing device 130 may begin to continue playing the audio track uponan input by the user indicating a desire to continue playing the audiotrack at the portable computing device 130. In one embodiment, theportable computing device 130 may begin to continue playing the audiotrack after the lapse of a predefined amount of time. In otherembodiments, the portable computing device 130 may begin to continueplaying the audio track once the portable computing device 130 is apredefined distance away from the POS display 110. Other examples arecertainly possible.

In one embodiment, the method 600 may further involve using the portablecomputing device and the software application to control a second mediasystem. That is, in some embodiments, the software application may beconfigured to cause the portable computing device to, at some time,control the POS display and to, at some time, control a second mediasystem.

In particular, the method may further involve the portable computingdevice discovering a second media system (e.g., a home system), wherethe second media system may include at least one media playback device.For example, the home system may include one or more zone players and ahome playback network. In one embodiment, discovering the second mediasystem may involve the portable computing device detecting the presenceof the second media system. In another embodiment, discovering thesecond media system may involve a user using a user interface on theportable computing device to initiate a discover procedure by thecontroller application on the portable computing device. The discoverprocedure may be similar to the procedure described above, whereby thecomputing device detects the presence of the second media system.

The method may further involve joining the software application on theportable computing device to the second media system using a systemidentifier of the second media system. Joining the software applicationon the portable computing device to the second media system display maycause the portable computing device to be enabled to control the secondmedia system via the software application. In some embodiments, joiningthe software application on the portable computing device to the secondmedia system may involve the portable computing device joining aplayback network of the second media system.

The system identifier of the second media system may indicate a uniqueGID and a unique set of configuration variables or parameters of thesecond media system, such as channels (e.g., respective frequencybands), SSID and WEP keys or other security keys. In other embodiments,the system identifier of the second media system may indicateidentifiers unique to the at least one media playback device (e.g., azone player).

In one embodiment, the home system may include a home playback network.The system identifier of the home system may indicate identifiers uniqueto the home playback network, which may cause the portable computingdevice to join the playback network of the home system.

The method may further involve sending from the portable computingdevice via the software application one or more commands to control theat least one media playback device of the second media system. Forexample, the portable computing device may send a zone player of thehome system a command to play an audio stream at the zone player. Otherexamples are also possible.

At block 701, the method 700 may involve sending a notificationregarding a POS display to a portable computing device, where the POSdisplay includes at least one media playback device. In someembodiments, the notification may include the same or similarindications as the notification described above with reference to FIG. 6. The notification may be sent by the local server 145 or the mediasystem server 150 (or a third party server) via the data network 140 ora cellular network, among other networks. In some embodiments, the POSdisplay 110 may include the local server 145, and the POS display 110may send the notification via the data network 140. Other examples arealso possible.

At block 702, the method 700 may involve transmitting a softwareapplication and a system identifier of the POS display to the portablecomputing device, where the system identifier may be used toautomatically configure the software application to control the at leastone media playback device. In some embodiments, the software applicationand the system identifier of the POS display may be the same as orsimilar to the software application and system identifier discussedabove with respect to FIG. 6 .

In one embodiment, the media system server 150 may transmit via the datanetwork 140 the software application and the system identifier to theportable computing device 130. In another embodiment, the POS display110 may transmit the software application and the system identifier tothe portable computing device 130 (e.g., from one of the zone players112-116 or the controller 118). The POS display 110 may have receivedthe software application and/or the system identifier from the localserver 145 and/or the media system server 150. In other embodiments, afirst device may transmit the software application and a second devicemay transmit the system identifier. For example, the system server 150may transmit the software application to the portable computing device130, and the POS display 110 may transmit the system identifier to theportable computing device 130. Other alternatives are also possible.

At block 703, the method 700 may involve joining the softwareapplication on the portable computing device to the POS display. Joiningthe software application on the portable computing device to the POSdisplay may cause the POS display to be controllable by the portablecomputing device via the software application. In some embodiments,joining the software application on the portable computing device to thePOS display may involve the portable computing device joining a playbacknetwork of the POS display (e.g., the portable computing device 130joining the playback network 120). In other embodiments, the joiningprocedures may be the same as or similar to the joining proceduresdiscussed above in reference to FIG. 6 .

At block 704, the method 700 may involve receiving from the portablecomputing device via the configured software application one or morecommands to control the at least one media playback device. For example,one or more of the zone players 112-116 may receive one or more commandsfrom the portable computing device 130 to output audio, join a synchronygroup, and adjust a volume level, among other examples.
